What does an air vent head do on a ship or tank?

It lets air and gas escape from an enclosed tank during filling or thermal expansion, while automatically closing to stop seawater or rain from entering, protecting the tank from both over-pressure and contamination.

What's the difference between float type and weighted type air vent heads?

A float type uses a buoyant ball that rises with liquid level to seal the vent automatically. A weighted type uses a hinged, spring or gravity-loaded flap that opens under vent pressure and closes by weight when pressure drops, typically used on larger or lower-pressure venting applications.

What sizes do you supply?

We supply air vent heads from 40A to 200A, covering small tank vents through large ballast and cargo tank systems.

What materials are available?

Cast iron, bronze, and cast steel, selected based on the tank contents (seawater, fuel, fresh water) and corrosion requirements.

Do air vent heads meet marine classification standards?

Our air vent heads are built to JIS F2005 standard, widely used and accepted for marine and shipboard tank venting applications.

Do you deliver outside Abu Dhabi?

Yes, we deliver across Dubai, Sharjah, and the wider UAE and GCC region, with fast turnaround from our Mussafah facility.
